Thread: Hitachi Desk star P7K500 hard drive

The Hitachi Desk star P7K500 HDP725050GLA360 has an unusual property: the manufacturer has the 3.5-inch hard drive the 24-hour continuous operation enabled for. This is the SATA/300 Desktop-Drive especially for home server and living room PC. Unlike the previous model Hitachi Desk star T7K500 HDT725050VLA360 relies on the Desk star P7K500 magnetic disks with a much higher data density. Therefore, instead of three now P7K500 range of two data panes to gross capacity of 500 GB to get one on.

The Hitachi Deskstar P7K500 HDP725050GLA360 works with the typical desktop hard drive 7200 revolutions per minute. The magnetic disk provides two are read-write heads. The buffer memory is 16 MB - common for this capacity class. When switched off, can the 500-GB hard disk up to 350 G and the operation is 70 G. This makes the Deskstar P7K500 the toughest desktop drives

The Hitachi Deskstar P7K500 HDP725050GLA360 offered very good but not exceptional transfer rate: The maximum data rate of 94.6 in reading and writing 98.2 MB / s. So they ended up in the test discipline in 8th place all previously tested 3.5-inch drives. In the medium data rate could well P7K500 with 78 MB / s down well and improved in this discipline to rank sixth The approximately 50 MB / s at the minimum transfer rate can be seen and to make the SATA/300-Desktop-Drive currently sixth fastest 3.5-inch hard drive in this measurement.

With access times, showed the 500-GB drive is not really responsive: they average was still satisfactory 5.9 milliseconds, with the measurement increased after activation of the automatic acoustic management (AAM) is only 0.2 milliseconds perfectly. At full stroke access the Deskstar P7K500 was 18.6 milliseconds, however, to date, the slowest 3.5-inch drive. This is the full stroke access time when the AAM only slightly increased to 19.2 milliseconds is no consolation - even if the Deskstar P7K500 so after all advances from last to fourth-last place.
